What to Focus On

  • An equation shows equality between two algebraic expressions.
  • Solving means finding the value that makes LHS equal RHS.
  • Same operations on both sides preserve equality.
  • The nth position has 2n + 1 matchsticks.
  • An equation can represent a pattern.
  • Trial and error works, but it is inefficient.
  • The tile pattern at Step k is 3k + 1.
  • Patterns can be checked by forming an equation.
  • A solution tells which step matches the required number.

Common Mistakes to Avoid

An equation can be changed on only one side and still remain true.

When a term is moved across the equal sign, its sign does not change.

If a factor is removed from one side, the other side should also be divided by that same factor only in the same-looking way, without checking the structure.

Memory Tips

Equation means equality between two algebraic expressions

Solving an equation

Same operation on both sides preserves equality
